A new study published in the Journal of General Internal Medicine finds that the use of patient decision aids increase a young women's reluctance to begin screening mammography. In fact, it is the use of decision aids for breast screening that led some women to forgo the screening.

In a systematic review and meta-analysis of three randomized trials, Oregon Health & Science University (OHSU) scientist Ilya Ivlev, found that, compared to typical care, 77 percent of women aged 38 to 50 who viewed a patient decision aid decided not to undergo screening mammography.

Option Grid™ decision aids for clinical encounters started in 2009 at the Decision Laboratory of Cardiff University, and has since developed into an international collaborative. Since 2013, Dartmouth College (New Hampshire, USA), has been supporting the development of Option Grid™ decision aids. According to the Ottawa Inventory of Patient Decision Aids, as of February 2015, the Option Grid Collaborative is the third largest developer of decision aids worldwide.
